But, Tata Motors today said that the Nano is a safe car with a robust design, state-of-the-art components and built with an uncompromising attention to quality in all aspects. This has been re-established through a second analysis, conducted during the months of September and October, Tata Motors said. Customers can be rest assured that there are no generic defects in the Tata Nano, it said.
"Besides, our customer satisfaction studies with current Nano owners indicate that about 85% are satisfied or very satisfied with the car, because of it being ‘small yet spacious’, its performance, maneuverability, durability, low operating cost and safety," Tata Motors said.
Some Nano owners have taken their cars on country-wide trips or to altitudes like Khardungla, the world's highest motorable road, according to Tata Motors. This adequately corroborates the Tata Nano's reliability and safety, as was seen during the validation of the car with about 300 prototypes, which covered more than 2 million km of safe operation before launch, it said.
The investigation, by a team of internal and international experts, has once again concluded that the reasons for the incidents in few Nano cars are specific to the cars which had such incidents, Tata Motors said. "We have noticed instances of additional foreign electrical equipment having been installed or foreign material left on the exhaust system. It is also our belief that as we penetrate deeper, the Nano will be bought increasingly by users in the hinterlands not fully familiar to cars," it said.
Taking all this into account, Tata Motors said it has decided to make the car even more robust. It will do this by providing additional protection in the exhaust system and the electrical system.
Beginning the third week of November, each owner will be informed about these measures, Tata Motors said. The option lies with the Nano customers on whether they would like to avail of these measures. This will be provided at no cost to customers. These actions do not constitute a recall, Tata Motors said.
As at the end of October 2010, Tata Motors has delivered over 70,000 Nano cars. The company has already declared open sales in Kerala (since August), and (since October) in Karnataka, Maharashtra, Uttar Pradesh and West Bengal.
Tata Motors said it was receiving good response from these states. Open sales will gradually be extended state by state, it said.
